com.geoway.mobile.core.MapPos

public class MapPos
extends java.lang.Object

A double precision map position defined using three coordinates. X and y coordinates denote positions on the map,
while z coordinate is height from the ground plane. Actual units for x, y and z depend on map projection.
For example, in EPSG:4326 x is used for latitude, y for longitude and z for height in meters.
